Discount Contribution Calculator
Your discount has a price tag the customer never sees.
A price cut can lift orders and shrink what the business keeps. Include product costs, shipping, fulfilment, allocated overhead and fees. See how many extra orders you would need to preserve the starting contribution.

Include the costs the business absorbs
The price cut has a second price tag.
A busier store is only useful if the extra orders pay for the discount. Follow what each order leaves behind.
Full-price contribution per order
R 450After the entered order costs and percentage fees; before advertising and any omitted overhead.
Discounted contribution per order
R 353Selling price after discount: R900.00.
Contribution at your current order volume
R 45 000100 full-price orders.
Discounted contribution at the same volume
R 35 300100 discounted orders.
Extra orders needed to keep contribution

The comparison uses your inputs and fixed assumptions. It is a planning example, not a prediction.
What is getting in the way?
Pick the problem you recognise. Start with a change you can actually measure.
- Compare a relevant bundle or threshold offer with a blanket discount, using contribution after acquisition.
- Include delivery subsidies, payment fees, returns and allocated overhead. Check the extra order requirement against stock capacity.
The maths behind your result
Contribution = selling price × (1 − percentage fees ÷ 100) − COGS − shipping subsidy − fulfilment − other entered per-order costs.
Discounted price = full price × (1 − discount ÷ 100). Required orders = round up(current contribution total ÷ discounted contribution per order).
Order mix and per-order costs stay fixed. This excludes ad spend and overhead not entered; it is not net profit. Enter values on a consistent VAT basis.
